Numerical Simulation of Strongly Nonlinear Wave-Ship Interaction by CIP/Cartesian Grid Method

摘要

A Cartesian grid method for three-dimensional computation of strongly nonlinear wave-body interactions is presented in this paper. The main feature of the method is the use of CIP (Constrained Interpolation Profile) method (Yabe et al., 2001). The free surface is captured by THINC scheme and a newly technique is developed to define a practical ship with complicated shape. The accuracy of the method is shown by a comparable computation with an experiment on a modified Wigley model. The efficiency of the method for practical ships is demonstrated by an numerical example with a container ship model.
